My sound only plays at a very low volume?

The speakers are built into speaker cabinets, which contain one or more drivers. The sound of these cabinets is influenced not only by the choice of driver but also the size and construction of the cabinets. In general, larger speaker cabinets (in relation to the diameter of the speaker) are able to produce a deeper bass output. Bass instrument speakers are typically mounted in more rigidly-constructed and heavily-braced cabinets than speakers for non-bass instrument amplification, because speaker cabinets for bass produce much more vibration. Most bass speaker cabinets employ a vented bass-reflex design, while others have sealed cabinets. Some cabinets use a transmission-line design which is similar to bass-reflex, and some very large cabinets use horn-loading of the woofers.
